| Outline of Final Research Achievements |
It is widely recognized that mechanical characteristics of the soil samples taken from the grounds with soil sampling technique involving stress-release and mechanical disturbance usually have different characteristics from the samples being in in-situ state. It is also believed that the influence of the soil sampling (stress release and disturbance) is more severe to soil samples with cementation than the samples without cementation. This research mainly investigates the influence of the soil sampling on the mechanical characteristics of the soil sample with the cementation effect.
